Construction of apparatus for destroying insects



UNITED STATES PATENT OFFICE.

ADOLPH ISAACSEN, OF NEW YORK, N. Y.

CONSTRUCTION OF APPARATUS FOR DESTROYING'r INSECTS.

Specification of Letters Patent No. 29,699, dated August 21, 1860.

To all whom it may concern.'

Be it known that I, ADOLPH IsAAcsEN, of New York, in the county and State of New York, have invented a certain new and- Improved Insect-Killer, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

My invention relates to and is an improvement on that class of insect killers which contain a noxious powder and inject it by a blast of air upon the infested parts.

My invention consists of a particular arrangement of parts, constituting a new article of manufacture, for this purpose,

In other instruments where a bag or ball of elastic material is used to' blow the powder the latter is placed in a separate reservoir, and a perforated partition placed between the ball and the reservoir. This arrangement works well except when inverted, when the perforated diaphragm does not prevent the powder from clogging in the nozzle. The majority of cases require the instrument to be used in this very position, in which all previous machines are inefhcient.

To enable others to construct and use my improved insect killer I will proceed to describe it by the aid of the drawings.

A is a bag or ball of india-rubber which is made to embrace the exterior of the lower end of the nozzle which is enlarged at this point into a chamber B, with a bottom of coarse gauze or wirecloth. The other end of the nozzle is a tube, C, for directing the powder in any direction desired.

To use my invention the nozzle, B, C, is removed, the bag A partially lled with a noxious powder, and the nozzle again inserted. Now, by holding the instrument in the fingers and placing the thumb on the bottom, in the manner shown in the drawings, the air is blown out through the tube C into or upon the infested place, and the agitation of the powder due to the lifting of the bottom by the thumb, insures the admiXture therewith of a liberal quantity of the powder, whether the instrument be held upright, inverted or inclined in any direction.

The wire cloth or perforated base, b, of the chamber B, must be sutliciently coarse to allow the passage of the powder through its interstices, but not sufficiently open to allow it to pass so freely as to clog in the nozzle C.

Having now fully described my improved insect killer, what I claim as new therein and desire to secure by Letters Patent, is`

The new article of manufacture herein described, composed of the rubber bag or ball A, the nozzle, B, C, and strainer arranged to operate together in the manner herein set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
